Top 5 Asphalt Problems and How to Fix Them

Top 5 Asphalt Problems and How to Fix Them”* – Common issues like cracking and potholing, and how to properly address them.

Asphalt surfaces are common in roads, parking lots, and driveways due to their durability and cost-effectiveness. However, they are susceptible to various problems over time. Here are the top 5 asphalt problems and how to fix them:

1. Cracking

Types of Cracks:

• Alligator Cracking: Resembles the skin of an alligator, caused by a weakened base or sub-base.
• Linear Cracking: Long, straight cracks typically caused by temperature changes or poor construction.

Fix:

• Alligator Cracking: Requires full-depth reclamation. Remove the affected area, repair the base, and repave.
• Linear Cracking: Can often be repaired with crack sealing. Clean the crack, apply a crack sealant, and allow it to cure.

2. Potholes

Cause:

• Water infiltration, freeze-thaw cycles, and traffic wear lead to the breakdown of the asphalt.

Fix:

• Clean the pothole of debris and loose material.
• Apply a tack coat to the sides and bottom.
• Fill with hot or cold asphalt mix.
• Compact the mix and ensure it’s level with the surrounding pavement.

3. Raveling

Cause:

• The loss of aggregate from the asphalt surface, often due to poor compaction or aging.

Fix:

• For minor raveling, apply a seal coat to bind the surface.
• For severe raveling, remove the top layer and repave.

4. Depressions

Cause:

• Poor compaction during installation or settling of the underlying soil.

Fix:

• For minor depressions, apply a leveling course of asphalt.
• For significant depressions, remove the affected area, address any issues with the sub-base, and repave.

5. Water Pooling (Bird Baths)

Cause:

• Poor drainage or an uneven surface leading to water accumulation.

Fix:

• Ensure proper drainage design during installation.
• For existing bird baths, mill the affected area to create a slope for drainage and repave with a thin overlay.

Preventative Measures

To minimize these issues, regular maintenance is crucial:

• Seal Coating: Apply every 2-3 years to protect the surface.
• Crack Sealing: Address cracks as soon as they appear to prevent water infiltration.
• Proper Drainage: Ensure good drainage design and maintenance to prevent water damage.
